Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Worn Components

Inspect Shocks/Struts:
- Remove the wheel to access the suspension components.
- Check for oil leakage around the shocks/struts indicating failure.
- If worn, remove the shock/strut assembly by loosening the upper and lower mounting bolts.
- Replace with new shocks/struts, ensuring to torque the bolts to manufacturer specifications.
Inspect Bushings:
- Examine control arm bushings for cracks or deterioration.
- If damaged, remove the control arm by loosening the mounting bolts.
- Replace with new bushings and reinstall the control arm, torquing bolts to specification.
Inspect Control Arms:
- Check the control arms for bends or cracks.
- If damaged, replace with new control arms following the manufacturer's service manual.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle back to the ground.
Recheck all fasteners for proper torque.
Test drive the vehicle to ensure the noise has been resolved.
